Based on land use vector data of Weihai from remote sensing interpretation in three periods, using land use spatial shape fractal model, fractal dimensions and stability index of each main land use type in 1985,1995 and 2000 were acquired. Using the methods of overlay analysis, etc, dynamic degree of each main land use type in 1985-1995, 1995-2000 and 1985-2000 were calculated. Based on these data stated above, the rule of land use fractal characteristic change and dynamic degree change were studied. The result of the research showed: In 1985, 1995 and 2000, fractal dimensions of unused land, urban land and water area were all bigger, and fractal dimensions of rural residents, other construction land were all smaller. From 1985 to 2000, even value of fractal dimensions of each main type of land use decreased gradually, and, in all, morphology of land use types became simpler and more regular. The changing features of fractal dimensions and stability index of each main type of land use differed more significantly among different periods. In the three periods, the spatial shape of rural residents, other construction land and unused land were more stable, and the spatial shape of water area, urban land, grassland and farmland were more unstable. In 1985-1995, the annual increasing rate of urban land was the highest and the annual decreasing rate of forest land was the highest; in 1995-2000, the annual increasing rate of urban land was the highest and the annual decreasing rate of water area was the highest; in 1985- 2000, the annual increasing rate of urban land was the highest and the annual decreasing rate of unused land was the highest; thus, urban expansion was fast and the trend of urbanization was very obvious in Weihai. Rapid development of society and economy, government planning, urbanization, and so on, were the main reasons for change of fractal dimensions, stability index and dynamic degree of land use in Weihai.
